• Semi-flexible pavement is a composite pavement that utilizes the porous pavement structure of the flexible bituminous pavement which is subsequently grouted with an appropriate cementitious material. The main purpose of this research is to investigate the influence of superplasticizer type and dosage on the flowability of cementitious grouts. The grout mixtures were designed to attain high compressive strength while maintaining flowable properties to ensure that the cement slurries infiltrate easily through the ungrouted samples and to fill up the voids under the influence of gravitational action. In order to attain the workability required, three types of superplasticizer were used. Two were of polycarboxylic ether polymer and the other was of sulphonated naphthalene formaldehyde origin. Results showed that type and dosage of superplasticizer influence the workability of the cementitous grouts.
